Had a major case of insomnia last nigt so im sharing all the things I found online. Here is a pretty cool dockable dvd player that offers the versatility of being able to be removed and used outside the vehicle but still looks like an installed unit because of the docking station. says you can install two docking units in two different vehicles and be able to use the player in both.
